(Mishnah - R. Meir): When a person is in pain, how is the Shechinah (Divine Presence) pained? 'My head is heavy. My arms are heavy.'

If the verse says that I am pained over the blood (pain) of Resha'im, all the more so over the blood of Tzadikim that is spilled!

(Gemara): Our text of the Mishnah says Kalini. Some texts say "Kal Ani'';

The one who teaches Kalini (like Kal Eini), it is an expression of Kalil (I am not light, rather, heavy). The one who teaches Kal Ani, it is an expression of Natil (a heavy burden, like "Koved Even v'Netel ha'Chol'' - Mishlei 27:3).

Our Mishnah [above, 29a] is unlike R. Meir, who says that even for a blasphemer he transgresses a Lav [if he leaves him hanging overnight. The Mishnah learns from "Lo Salin... Ki Kilelas Elokim Taluy.'' R. Meir expounds this verse to teach about the Shechinah's pain.]

(Mishnah): Not only this - rather, anyone who leaves his Mes overnight (unburied) transgresses a Lav;

If he left him for his honor, to bring a coffin or shrouds, he does not transgress a Lav.

They would not bury [someone executed] in the cemetery of his ancestors. Rather, Beis Din has two cemeteries, one for Niskalim and Nisrafim (those stoned and burned) and one for Neheragim and Nichnakim (killed by the sword and choked).

(Gemara - Beraisa): If one moves a coffin from place to place, [the Aveilus] of gathering bones does not apply.

(R. Acha): This applies to a marble coffin, but a wood coffin, gathering bones applies [to moving it].

(R. Yosi): Even a wood coffin, gathering bones does not apply to it. (KORBAN HA'EDAH - even this is considered as if they were buried the entire time. R. Acha holds that only in a stone coffin, they are considered buried.)

Question: [If so, according to R. Yosi,] what is gathering bones? (The Yerushalmi in Mo'ed Katan 1:5 answers, it is when they are moved in an inner garment.)

(R. Chagai): (If he was not there when they were moved, he does not conduct Aveilus.) This is if he heard the next day, but the same day, [Aveilus due to] Shemi'ah applies to gathering bones.

(Nikomachi, in front of R. Zeira): There is no Shi'ur to gathering bones.

R. Mani ruled for R. La of Kafra to tear and mourn like R. Acha, but not to become Tamei (if he is a Kohen), like R. Yosi. (His Mes was moved in a wood coffin.)

(Beraisa): Gathering bones is like a Shemu'ah (hearing that a relative died. He conducts Aveilus that day.) What is gathering bones? It is one who gathers bone by bone, after the flesh was consumed.

(Beraisa): Gathering bones - we do not say lamentations over it, nor Birkas Avelim;

Birkas Avelim is what we say in the Beis ha'Keneses. Tanchumei (consolation of) Avelim is what we say in the consolation line.

(Beraisa): However, we say matters over them. What are matters? Rabanan of Kisarin say, they are praises [of Hash-m, who kills and revives].

(Mishnah): After the flesh has decomposed (the deceased received atonement), they gather the bones and bury them in their place (with his ancestors).

His relatives greet the witnesses and judges, i.e. "know that we do not bear a grudge, for you judged correctly.''

[The relatives] do not mourn (Aveilus), they conduct Aninus, for this is only in the heart.

(Gemara - Beraisa): Initially, they would gather the bones and bury them in deep pits (without a coffin, so the flesh will be consumed). When the flesh was consumed, they would gather them and bury them in cedar coffins;

That day he would mourn, and the next day he was happy, to say that his fathers are no longer being judged (since the flesh was consumed).

(The Mishnah (29b) said that they would not bury him in his ancestors' cemetery. Not only this, rather, they bury them by themselves - Niskalim with Nisrafim [in one cemetery], and Neheragim with Nichnakim [in another cemetery].

This is what David said "Al Te'esof Im Chata'im Nafshi'' - this refers to ha'Niskalim and ha'Nisrafim; "v'Im Anshei Damim Chayai'' refers to ha'Neheragim and ha'Nichnakim.
